√((25x^9y^3)/(64x^6y^11)) doing the normal division within the radical

√((25x^3)/(64y^8) then looking at the squares within the radical...

√((5^2*x^2*x)/(8^2*y^8)) now we can move out the perfect squares...

(5x/(8y^4))√x

So it is the bottom answer...

The measure of angle A is 15°, and the length of side

dangina [55]

Answer:

Part 1) $AB=30.9\ units$

Part 2) $AC=29.9\ units$

Step-by-step explanation:

The picture of the question in the attached figure

Part 1

Find the length side AB

we know that

$sin(A)=\frac{BC}{AB}$ ----> by SOH (opposite side divided by the hypotenuse)

substitute the given values

$sin(15^o)=\frac{8}{AB}$

solve for AB

$AB=\frac{8}{sin(15^o)}=30.9\ units$

Part 2

Find the length side AC

we know that

$tan(A)=\frac{BC}{AC}$ ----> by TOA (opposite side divided by the adjacent side)

substitute the given values

$tan(15^o)=\frac{8}{AC}$

solve for AC

$AC=\frac{8}{tan(15^o)}=29.9\ units$

Help me on this please

steposvetlana [31]

I got you hun!

27= 3x is the equation you will need

27 is the total the coach needs making it the total. Since each pack comes with 3 you will mutiply the amount of pack, or x, by 3.

X=9

we know this because if you divide 3 by 27 to get it on the other side we get 9. This means the coach needs to buy 9 packs of baseballs for the team.

27=3(9)

Hope this helps!

The area of Erin's circle to the nearest hundredth is 50.24 in².

<h3>What is the area of the circle?
</h3>

A circle is a bounded figure which points from its center to its circumference is equidistant.

Area of a circle = πr²

Where :

π = pi = 3.14
R = radius

3.14 X 4²

(3.14) (4) (4) = 50.24 in²

Find the missing angle measures in the triangles

Svetllana [295]

For the first triangle, I believe the given angles are 85 and 53. If I am incorrect, please let me know and I'll resolve it.

The answer for 1 would be 42.

2nd triangle- 69 is the missing angle measurement.

3rd- 64 degrees.

4th- 53

The reasoning behind all of these: The total of all three interior angles should be 180 degrees. So when you add the two GIVEN angles, and subtract that from 180, this answer is your missing angle.
